I like the SKS, but it's no T81. The T81 has a much better safety, is lighter and handier, takes magazines without stupid duckbills, and has adjustable gas system and pistol grip standard. It's a more feature rich gun.
It would be like saying a Remington 742 is better than a FN-FAL because it's cheaper and shoots the same ammo. That doesn't make it true to most people who would have to use one.
